摘要： Digital broadcast receiving terminal apparatus which receives multi-channel digital broadcast signals to record the huge capacity without deteriorating the quality of signals and to visualize the digital broadcasting. The outputs form the error correction decoding circus 4 are applied to the TS processor 12 via the switches SW 1 and SW 2, at the same time they are applied to the recording program selector 11. The recording program selector 11 applies the encoded data of the predetermined program to the digital interface 13, the digital interface 13 inputs and outputs the encoded data through bus in the IEEE1394 specification for example. Thus, the encoded data are applied to the external equipment and recorded as they are, and the degradation of the quality can be prevented. The switches SW 1 and SW 2 changes the receiving signals and the outputs from the digital interface 13 and applies them to the TS processor 12. The TS processor 12 depacketizes the input encoded data. Therefore, the image reproduction based on the receiving signals or the outputs from the external equipment can be carried out.

摘要： Video signals are encrypted so that only the privileged viewers can watch them. A layer coding unit divides video signals into two layers and encodes each layer. An encrypting unit encrypts the low-quality layer data items according to the setting signal from a secret level setting unit and supplies the encrypted signal to a combining unit. Another encrypting unit encrypts the high-quality layer data items according to the setting signal from a secret level setting unit and supplies the encrypted signal to the combining unit. Ideally the high-quality layer data items are encrypted at a secret level that is higher than the secret level used to encrypt the low-quality layer data items. The synthesized data from the combining unit is converted at a communication modem into communication data, which is transmitted to a reception apparatus.

摘要： A PLL circuit for use in a digital broadcasting receiver includes a receiver for receiving a bit stream containing program clock references (PCRs) transmitted from a broadcast station. The PCRs correspond to a frequency and phase of a transmitter system clock. The circuit also contains an oscillator for generating receiver system clocks, a counter responsive to the system clocks, and a connection to allow the bit stream to flow from the receiver to the oscillator. A controller controls the counter based on differences between the PCRs in the bit stream and the counter output. A load control means successively loads the PCRs on the counter in their order of transmission to lock the frequency and phase of the receiver system clock provided from the oscillator with the frequency and phase of the transmitter system clock. This arrangement allows quick adjustment of the receiver system clock frequency and phase by removing the influence of the insertion intervals of the PCRs in the bit stream when making the adjustment.

摘要： A demultiplexer unit separates a transport stream (TS) of an input digital broadcast into video information and audio information. A video decoder decodes the video information output from the demultiplexer unit to output a video signal. An encoder encodes the video signal output from the video decoder. A buffer stores the audio information output from the demultiplexer unit. A remultiplexing unit multiplexes video information encoded by the encoder and the audio information stored in the buffer. An HDD stores the video and audio information multiplexed in the remultiplexing unit.

摘要： A demultiplexing/GOP head detecting section detects a PCR value, while a recording/reproduction control section records a video or audio packet in a bit stream file and records information on the number of packets every PCR value and GOP. In reproduction, a reproduction position corresponding to a shift time is judged on the basis of information on the number of packets at every PCR value and GOP. This improves the shifting and returning speeds to time shift reproduction.

摘要： A system capable of performing compatible transmitting and receiving processes, regardless of whether a TV signal on the transmission side is a high-resolution signal or a low-resolution signal or whether the reception side includes a high-resolution display unit or a low-resolution display unit. On the transmission side, a frequency division circuit divides a high-resolution TV signal into signals in a plurality of frequency bands. The signals in each frequency band are converted into signals of a horizontal and vertical low band (a low-resolution TV signal band). The converted signals are coded by coding units, which transmit the coded signals. On the reception side, the coded signals multiplexed on the transmission side are separated and decoded at decoding units. A frequency synthesizing circuit restores the frequency bands of the decoded signals to the original bands. Then, the resulting signals are displayed with a high resolution. A low-resolution signal is coded and then transmitted. The coded signal is decoded on the reception side. The decoded signal is interpolated at an interpolation circuit. The interpolated signal is then displayed on a high-resolution display unit.

摘要： A main signal as the existing television signal and a helper signal for high definition are prepared in a transmitter. The energy of the main signal for a plurality of pixels is sequentially detected by an energy detector constituted by an absolute value circuit and an accumulator. The helper signal is controlled by a level controller, constituted by an adder and a divider, in such a way that its level follows according to the level of the detected energy. The level-controlled helper signal is frequency-multiplexed with the main signal having a frequency band of a removed region by a frequency multiplexer. A frequency-multiplexed signal separator of a receiver separates the mutiplexed signal into the main signal and the helper signal. The energy of the separated main signal for a plurality of pixels is sequentially detected by an energy detector constituted by an absolute value circuit and an accumulator. The separated helper signal has its frequency band restored to the original band from the removed region by a frequency domain restoring circuit. The restored helper signal is subjected to level control by a level controller, constituted by an adder and a multiplier, in the opposite characteristic to that of the sender side in accordance with the level of the detected energy.
